Description
Technical field
The utility model relates to a kind of self-latching relay, belongs to control field.
Background technology
Current, in the controlling, if relay will keep, need power supply to maintain, so maintain relay operation to need more electric energy.
Summary of the invention
The utility model relates to a kind of self-latching relay, to realize relay also to keep its operating state object in power-down conditions.
For realizing above-mentioned object, the utility model adopts following technical scheme:
A kind of self-latching relay, comprises:
Shell (1), left electromagnet (2), right electromagnet (3), left moving contact (4), right moving contact (5), left fixed contact (6), right fixed contact (7), spring leaf (8), lower-left binding post (9), upper left binding post (10), bottom right binding post (11), upper right binding post (12), lower controlled terminal (13), the controlled terminal in upper left (14), the controlled terminal of upper right (15); As shown in Figure 1.
Below in conjunction with accompanying drawing, technical construction of the present utility model and method are described: left electromagnet (2), right electromagnet (3), left moving contact (4), right moving contact (5), left fixed contact (6), right fixed contact (7), spring leaf (8) is installed on the inside of shell (1) respectively, two binding post lower-lefts binding post (9) of left electromagnet (2) and upper left binding post (10) provide electric energy for left electromagnet (2), two binding post bottom rights binding post (11) of right electromagnet (3) and upper right binding post (12) provide electric energy for right electromagnet (3), left moving contact (4) and right moving contact (5) are a magnet piece with permanent magnetism respectively, left moving contact (4) is arranged on the left side of spring leaf (8), right moving contact (5) is arranged on the right side of spring leaf (8), left moving contact (4) is left fixed contact (6) to contact, left fixed contact (6) is connected with the controlled terminal in upper left (14), right moving contact (5) is right fixed contact (7) to contact, right fixed contact (7) is connected with the controlled terminal of upper right (15), spring leaf (8) is connected with lower controlled terminal (13), before not working, because left moving contact (4) and right moving contact (5) are permanent magnet, therefore, its state then must have one end to be inhaled closed by left electromagnet (2) or right electromagnet (3), when needs Reverse Turning Control, only need to add inverse current on left electromagnet (2) and the corresponding electromagnet of right electromagnet (3), after complete operation, then relay does not need to add power supply again, then be kept closed.
The beneficial effects of the utility model: structure is simple, energy-conservation, reliable operation.
accompanying drawing illustrates:
Accompanying drawing 1 is structural representation of the present utility model.
embodiment:
In order to make the technical solution of the utility model clearly understand, below in conjunction with drawings and Examples, further describe the utility model, instantiation described herein, only in order to explain the utility model, is not limited to the utility model.
embodiment:
Refer to shown in accompanying drawing 1, left electromagnet (2), right electromagnet (3), left moving contact (4), right moving contact (5), left fixed contact (6), right fixed contact (7), spring leaf (8) is installed on the inside of shell (1) respectively, two binding post lower-lefts binding post (9) of left electromagnet (2) and upper left binding post (10) provide electric energy for left electromagnet (2), two binding post bottom rights binding post (11) of right electromagnet (3) and upper right binding post (12) provide electric energy for right electromagnet (3), left moving contact (4) and right moving contact (5) are a magnet piece with permanent magnetism respectively, left moving contact (4) is arranged on the left side of spring leaf (8), right moving contact (5) is arranged on the right side of spring leaf (8), left moving contact (4) is left fixed contact (6) to contact, left fixed contact (6) is connected with the controlled terminal in upper left (14), right moving contact (5) is right fixed contact (7) to contact, right fixed contact (7) is connected with the controlled terminal of upper right (15), spring leaf (8) is connected with lower controlled terminal (13).
